Will Anderson 93358505fc Harden prod: security, autoscaling, observability, BuildKit CI
Security:
- Drop ALL capabilities, enforce non-root, RuntimeDefault seccomp on
  neuron-mcp, neuron-rest, neuron-marketing pods
- Add startup probes (150s window for JVM) so liveness doesn't fire early
- Replace docker-sock hostPath with BuildKit rootless TCP endpoint
  (moby/buildkit:v0.19.0-rootless) — removes node root access from CI
- Document full ESO AppRole migration path in cluster-secret-store.yaml

Autoscaling & availability:
- HPAs on mcp (1–6), rest (1–4), marketing (2–8) at 65–70% CPU
- PodDisruptionBudgets (minAvailable: 1) on all three services
- NetworkPolicy: default-deny-all in neuron-prod, explicit allow rules
  for Traefik ingress, intra-namespace, and egress to DNS/platform/vault

Observability:
- ServiceMonitors for mcp, rest, marketing (cross-namespace enabled in
  kube-prometheus-stack with serviceMonitorSelectorNilUsesHelmValues:false)
- PrometheusRules: high error rate, high latency, crash loops, replica
  shortage, Postgres down/connections, backup failure, backup staleness

Chart version pinning:
- kube-prometheus-stack, loki, tempo, redis, alloy, postgres — all pinned
  to major-version ranges to block silent breaking upgrades

Backup hardening:
- restic:latest → restic:0.17.3 (deterministic image)
- Weekly backup-verify CronJob: restores latest snapshot and validates
  SQL dump structure (≥5 CREATE TABLE, pg_dump header check)

ArgoCD:
- neuron-prod AppProject: scopes deploys to neuron-prod + platform ns,
  blacklists ClusterRole/ClusterRoleBinding/Namespace creation,
  automated sync window 2–6am UTC, manual always allowed
